arranged just below the agitator. The plug sage 7c is a straight-throughpassage which controls, the flow of the beverage, and the passa-ge'l is"a right-angle passage which con-- trols the gas supply. When the plug jis turned through. a rightangle in a clockwise direction from theposition shown in the drawing, the beverage and the carbon dioxid bothpass to the chamber a. \Vhen the plug is turned through a right angleclockwise direction from the position shown in thedrawing, the beverageflows from the tap but no gas is allowed to mix with it. .The degree ofcarbonation given to the total quantity of beverage drawn ofi into theglass, etc., may-be varied by turning the tap in the clockwise directionto yield a quantity of highly carbonated beverage and then thevgla'ss,'etc.

In the modification shown in Figs; 2, 2', 2 -2, the plu 1' has threeports or passages k Z m T e arrangement of 'portsshown in these figuresis found to work most satisfactorily in practice. -The port k which hera is a straight-through port. The port Z? which controls thegas supplyis a right- .angled port, each. of its limbs making an acute angle withthe center line of the port kJa-The port m extends upward from thebottom of the plug 7' and has a horizontal limb which broadens outtoward the circumference of the plug j as indicated in Fig. 2. W'Vhenthe plug j is turned through a right sition shown in the drawings, thebeverage passes to the chamber (1 hen the liquid has risen to a certainheight in the chamber a itcloses a valve n of any suitable construction.The further escape of am from the chamber a is thereby prevented, andthe flow of beverage into the chamber ceases as soon as the backpressure in the channel 0 equals the pressure in the cask, .etc. Whenthe plug 7' is turned fart-her 1n the clockwise direction,-the ort k isclosed but the port l is open an allows gas to bye-n agitator or stirrerc riven in counter p 7 has two ports'or passages is, Z, The pasturningthe't'apin the other direction to fill controls the entry of beverage tothe chaniangle in a clockwise direction from the popass from the pipe 6to the pipe p. The

gas issues from small holes in the upper part (Z or". the pipe anddrives the agitator The flow of the gas ceases when the internal pressurin the chamber a reaches the pressure in the gas supply pipe 6. hen theplug j is turned still farther in the clockwise direction, the portv isclosed, but the port in is opened to the passage 4 The carbonatedbeverage then flows into the glass, etc, held below the. tap, the valven permitting air to enter the chamber a to take its place. When the plugj turned through a right angle in counterclockwise direction from theposition shown in the drawings or through three right angles in aclockwise direction, the ports k and m are opened, but the other portsare closed. Beverage then passes through the chamber a and thence to theglass, etc, without being carbonated.- The spindle which carries theagitator may be adjusted by means of a set screw 1*. T he degree ofcarbonation can be varied to suit the taste of the consumer by drawingoil one or more charges of can bonated beverage and then filling up theglass with uncarbonated beverage.

In the arrangement shown in Figs. 3 and 4 a mixing chamber a isconnected by a pipe A to the usual pump B bolted to a block C. When thehand lever D is pulled.

to-thc leftthe beverage passes from the pump to the chamber a and thenceto the? ordinary delivery pipe E. The supply of gas to the mixingchamber is controlled by a valve F, which is opened as the lever D makesthe first part of its full stroke and is allowed to remain closed duringthe latter part of the full stroke of the lever D. \Vith thisarrangement the degree of carbonation of the beverage drawn otf into theglass, etc, held below the pipe E can be readily varied by dwelling moreor-less on the first part of the full stroke of the lever D. Themechanism foroperating the valve F comprises a rod G which is pivoted atG and is oscillated by a connecting rod X pivoted in any suitableposition on the lower part D of the beer engine lever D. The rod G haspivoted to it at H a pawl or trip-.piece H, which so loaded that itnormally occupies the position shown, its rear dge resting against astop H on the rod G. Then the rod is raised from the position shown, thepawl H engages an arm I carried by a pivoted bar J. The arm 1 is thusturned to the left and pulls with it a connecting rod K, which has itsother end secured in a suitable manner to the lever L, which lever Loperates the spring-controlled spindle of th valve F. Thus, when the armI is pressed back, the lever L is vibrated and the valve F is opened.\Vhen the rod G has been raised. through a predetermined distance, whichmay be any fraction of its complete stroke. the tip H of the pawl Hslips past.

" ipaasoo the tip 1 of the arm I, thus allowing the spring to close thevalve F and to return the parts L, K and I to their original positions.During the remainder of the stroke of the lever D, the valve F remainsclosed and the beverage which passes through the chamber (5" to thedeliverypipe E is uncarbonated ll'hen the lever D makes its returnstroke, the pawl H strikes the tip I of the arm I. The pawl H is therebyturned about the pivot H until its tip H slips past the tip I, afterwhich 'the parts resume the position shown in the drawing. The agitator0 Fig. 4, is supported in the mixing'chamber a by means of a bridgepiece L having anadjustable bearing screw r and by means of a hollowpiece M through which the gas passes. The piece 'M is secured in placeby an ordinary screw N and by a hollow screw 0 through which the gaspasses from the channel P. A lead or otherwasher Q insures-a tight jointbetween the end of the piece M and the wall of the chamber (1 The gasissues from the piece M by way of two or more small holes R and thusdrives the agitator Filtering material S, Sfo'f any nature is inclosedbetween perforated plates T, U, and T, U.

In-the various forms described it will be noticed that strainingorfiltering means have been introduced. These strainers or filters arefound in practice to assist greatly in reducing the size of the bubblesof gas, thus, in conjunction with the revolving agitators, giving to thebeverage a persistent creamy head Moreover, the strainers produce aneven flow of liquid by preventing the gas from forcing the beverageviolently fromthe apparatus.

The carbon dioxid is supplied to each of the various forms of apparatuseither from a gas reservoir, which is preferably fitted with a reducingvalve and gage, or from a small generating plant;

The forms of apparatus described may be modified to any extent providedthat they retain the following principle, viz :that the degree ofcarbonation can be readily varied to suit the taste of each individualconsumer by mixing a variable quantity of beverage carbonated as it isdrawn ofi from thetransport receptacle with a variable quantity ofbeverage not so carbonated, the

carbonated portion being agitated during absorption of the carbon dioxidby an agitator driven by the pressure of the carbonating gas.
